三节点mysql用户互信方法

三台机器之间mysql用户ssh互信配置切换到如下路径，执行相关操作cd /home/mysql/.ssh(1)在所有的主机上执行：ssh-keygen -t rsa # 在每台都需要操作，一路回车,生成一对公私钥。(2)节点1执行ssh-copy-id -i id_rsa.pub mysql@devdb02ssh-copy-id -i id_rsa.pub mysql@devdb03(3)节点2执行ssh-copy-id -i id_rsa.pub mysql@devdb01ssh-copy-id -i id_rsa.pub mysql@devdb03(4)节点3执行ssh-copy-id -i id_rsa.pub mysql@devdb01ssh-copy-id -i id_rsa.pub mysql@devdb02#测试(强烈建议)ssh devdb01ssh devdb02ssh devdb03
